Bupe Dulled effects of Ketamine whilst on subutex/buprenorphine

[aesthetic.addict]

Have anyone else experienced this? I find it impossible to k-hole while taking bupe, and the anxiolytic and antidepressants effects seems much lesser as well?
Different batches can work better than others though but no k hole. Have had over a years break from it, and has gotten on bupe in the meantime
